Introduction to E-Invoicing KSA API

Introduction to E-Invoicing
Electronic invoicing will be rolled out in two phases in KSA. For the first phase, enforceable as of December 4th, 2021, for all taxpayers (excluding non-resident taxpayers), and any other parties issuing tax invoices on behalf of suppliers subject to VAT, electronic invoice issuance will be very similar to today, with invoices issued through a compliant electronic solution and including additional fields depending on the type of the transaction.
What is E-Invoicing?
​​​​​​What is E-Invoicing (FATOORAH)?
Electronic invoicing is a procedure that aims to convert the issuing of paper invoices and notes into an electronic process that allows the exchange and processing of invoices, credit notes & debit notes in a structured electronic format between buyer and seller through an integrated electronic solution.
What is an electronic invoice?
A tax invoice that is generated in a structured electronic format through electronic means. A paper invoice that is converted into an electronic format through copying, scanning, or any other method is not considered an electronic invoice.

How does E-Invoicing (FATOORAH) work?
E-Invoicing will be rolled out in two phases in KSA.
For the first phase, enforced as of December 4th, 2021, for all taxpayers (excluding non-resident taxpayers), and any other parties issuing tax invoices on behalf of suppliers subject to VAT, electronic invoice issuance will be very similar to invoices generated prior to 4 Dec 2021, with invoices issued through a compliant electronic solution and including additional fields depending on the type of the transaction.
For the second phase, enforceable starting January​ 1st, 2023 in waves, the electronic solution must be integrated with ZATCA's systems, and e-invoices should be generated in the required format.
What are the required fields for the e-invoice in phase one (generation phase) and phase two (integration phase)? ​

Roll-out phases
​ZATCA has published e-invoicing requirements that will be rolled out into two main phases in KSA:
PHASE 1 (as of December 4th, 2021) 
Phase 1, known as the Generation phase, will require taxpayers to generate and store tax invoices and notes through electronic solutions compliant with Phase 1 requirements. Phase 1 is enforceable as of December 4th, 2021, for all taxpayers (excluding non-resident taxpayers), and any other parties issuing tax invoices on behalf of suppliers subject to VAT.
PHASE 2 ​ (starting from January 1st, 2023) 
Phase 2, known as the Integration phase and rolled out in waves by the targeted taxpayer group, will involve the introduction of Phase 2 technical and business requirements for electronic invoices and electronic solutions, and the integration of these electronic solutions with ZATCA’s systems.
ZATCA will notify taxpayers of their Phase 2 wave at least six months in advance, and the enforcement date for the first target group will not be earlier than January 1st, 2023.
